Police and trained weather spotters reported seeing several funnel clouds above Rockford Wednesday afternoon as a severe storm system passed through the area.

The Winnebago County Sheriff's office received several reports of rotating clouds in the sky shortly after tornado sirens went off shortly after 4 p.m.

Tornado sirens were activated once the National Weather Service issued a tornado warning for Winnebago County.

Funnel clouds, which can quickly turn into a tornado if weather conditions allow, were spotted over southwest Rockford and, near Harrison Avenue and Perryville Road and about the Rockford Mass Transit District transfer station in downtown Rockford.

There was one report of a possible tornado in southeast Winnebago County, Sheriff Dick Meyers said, but sheriff deputies found no evidence of a tornado.

"The weather spotter thought it may have touched down," Meyers said. "But when the squads went out there, they didn't see an signs of touch down. That's where they did see some hail damage, but nothing that would indicate a tornado."
